Quadricyclane (1) readily undergoes [2+2+2] cycloaddition reactions with electron-deficient fluorinated carbonylcompounds to give polyfluorinated 3-oxatricyclo[4.2.1.02,5]non-7-enes in high yields. Hexfluoroacetone, trifluoroacetyl chloride, methyl trifluoropyruvate, α-(fluorosulfonyl)difluoroacetyl fluoride, and bis(trifluoromethyl)ketene all react rapidly with 1. Trifluoracetyl fluoride although

The behaviour of ClOSO2F towards acetylene and the CN bond of perfluorocarbon acid nitriles as well as a possibility of CN bond cleavage in perfluoronitroso compounds were studied. Investigation of the chlorinating activity of ClOSO2F was continued. The addition reactions of IOSO2F to double bonds of fluoroolefines as well as the reactions of S2O6F2 with ethylnitrobenzenes were realized.

On the enteraction of perfluoroalkyl carbanions with silver salts
Perfluoroalkyl derivatives of silver may be produced by reacting fluoroolefins with silver salts in the presence of alkali metal fluorides in dimethylformamide, 1,2-dimethoxyethane or acetonitrile as a solvent. 19F NMR spectra and certain reactions of these compounds have been investigated.

The present invention provides novel fluorine-containing copolymers which comprise at least one fluorinated olefin, at least one polycyclic ethylenically unsaturated monomer with a fused 4-membered heterocyclic ring and, optionally, other components. The copolymers are useful for photoimaging compositions and, in particular, photoresist compositions (positive-working and/or negative-working) for imaging in the production of semiconductor devices. The copolymers are especially useful in photoresist compositions having high UV transparency (particularly at short wavelengths, e.g., 157 nm) which are useful as base resins in resists and potentially in many other applications.

Cycloaddition reactions of norbornadiene with fluorinated heteroaddends (hexafluoro-acetone, dichlorotetrafluoroacetone, trifluoroacetonitrile, and N-trifluoroacetylhexafluoro-propan-2-imine) were studied. As a rule, the reactions follow the concerted mechanism. The reaction with bis(trifluoromethyl)ketene gave a mixture of tricyclene [2+2]- and [2+2+2]-cyclo-adducts formed along different pathways
